13 Claims.

!I-l1e present invention relates to shoe machinery, and more :particularly to machines adapted Itoperform .duringasingle cycle of actuation the two operations of cutting shoe upper blanks such .as Vamps, tips, quarters, foxings, straps, or the like to form ornamental cutouts, edgings, 'and/or perforations therein or thereon and of applying inkor other marking substance toisaidblanks in the formof lines which function as guides .for subsequent operations such, for examplaas the application-of ornamental stitching .to the blanks or the assembly therewith in proper positionof other work ,pieces .for securementby stitching, adhesion, or otherwise.

.In-ccnnection with the foregoing it should be noted thatthe cuttingoperationreferred to may include the punching of perforations arranged in a pattern or design, or it may be the cutting out of one or more fairly largeopenings of-ornamental or utilitarian nature, or'it may be in the nature of pinkingor :for-ming ornamental {edges on the work, as is the case of a wing tip or foxing. All of .these cutting operations are within the purviewof the present invention.

The :production of such markings and perforations, edgings, or cutouts was formerly accomplished onlyby separate operations, the work being marked by hand or by :a suitable :die in one machine and beingperrforated -or cut :by hand or by .a suitable die in another machine. Comment need not be made here on the slowness of manual procedure, buteven with the use of two machines there were several ='disadvant'ages. One of these was the difficulty "of getting, 'for the operation performedsecond in order, the highly desirable identical work *piece gauging used for the first performed operation, and while' such gauging was not easy to achieve even with relatively stiff workpieces, it'was extremely difficult and-sometimes impossible with work pieces made of .thin, soft, or light material. A second disadvantage lay in the fact that since two machines necessitated twohper-ations, there was a doubling of apparatus rand amount of labor, the latter causing .a timestretch-out because the two operations occurred .in sequence in contrast to a singleoperation combining th results'of the two.

.In the .pastiew "years a distinct advance has been made in theart by the introduction of combined marking and cutting machines, i. .e., imachines so constructedas to perform the two operations of marking and cutting simultaneously or during a single cycle of actuation of a single machine. The advance which .such machines have'madeha's been recognized by all shoe manufacturers, but these machines are What maybe called of a special type, one requiring the purchase of an entire unit, including a ,press as a part thereof, and such machines are therefore quite expensiive.

But as individual marking machines and individual cutting machines areand long jhave been standard equipment among shoe manufacturers, it will be 'seen that in addition .to the factor of expense of the combined machine, that machine has brought into being a situation"such that while the individual machines have been rendered idle for all work done by'the combined machine, the utility of "the individual machines has not been diminished for theirsingle functions, a very important point since not allwork pieces which require marking on the one hand or cutting'on the other, require both. The coinbined machine therefore has not'been a complete substitute for the individual machines, and "in view of this situation, together with the expense involved, many of the smaller shoe Jmanufacturers have not purchased the special combined machine.

However, the admitted advantages of such combined machines have created a demand for inexpensive single apparatus which performsthe two operations of marking and cuttingyahd as a result constructions have been proposed which may be readily and 'removably installed in "any of the old and well known press machines built merely for various cutting operations, thereby transforming them into combined marking and cutting machines, This type of structure does not involve the expense of acquiring a special entire machine'and in addition to this the function of a marking machine is added to thatof the already existing and owned cutting machine so that by the installation of inexpensive apparatus shoe manufacturers may have individual or combined machines at will.

The present invention relates specifically to such installed apparatus, and it is the principal object of the present invention to provide inexpensive equipment by which the'two operations of cutting and guide line forming may be performed in a single machine during a 'singlecycle of the actuation thereof.

In my copending application, Serial No. 197,447, filed March 22, 1938, one example of such apparatus is disclosed and claimed. It is a further'obje'ct of the preesnt invention to provide several improvements in the mechanism disclosed .in .my said application, these improvements relating both to the die structure thereof and to the remainder of the apparatus, and to their mode of operation.

To the accomplishment of these objects and of such others as may hereinafter appear, the various features of the present invention reside in certain constructions, combinations, and arrangements of parts, hereinafter fully described and then pointed out in the appended claims, the

advantages of which will be readily appreciated by shoe manufacturers and others skilled in the art.

The various features of the present invention will be readily understood by reading this specification with reference to the accompanying drawings, which drawings ilustrate the best physical embodiment of the invention at present known to the inventor and in which:

Fig. 17 is an enlarged detail view in re r l vamachine is provided with a bed 25 (Figs. 1, 3-5) I and with a slide or plunger 26 which i vertically reciprocable in ways 2'! toward and away from the bed and is operatively connected, through the usual .treadle-operated, one revolution clutch (not shown) to some suitable source of continuously supplied power such as a flywheel-provided motor. The plunger 26 carries at its bottom face a platen or pressure member 28 having an under facing 29, and a rod 3!! mounted in ears 3| at the front of the machine frame 32 functions to guide rearwardly and beneath the facing 29 the usual strip of paper backing 33 (Fig. 5) to prevent cutting of the facing by cutting die elements, as is well understood. The frame 32 rests on a bench 34 (Figs. 1, 16) before which an operator stands, and the bed 25 is provided with a rearwardly extending guide member 35 (Figs. 15) medially located between the opposite sides of the bed. Further details of the Knight structure may be found in the above Knight patent and need not be set forth here, but the Knight structure is to be considered for th present invention, as being merel representative of numerous and well known but structurally differing cutting machines, as it will be readily understood that physical embodiments of the present invention may be used in many different press machines and are not confined to use in only the particular machine herein selected for purposes of disclosure. For example, although the illustrated embodiment employs a table corresponding roughly to the anvil structure shown in the above Knight patent, the present invention is applicable to machines which employ neither an anvil nor a table, and is applicable for use with elevated dies and in flat bed machines in which there is no anvil or table nor any elevated die at all; a flat bed die being used.

Adapted to rest upon and b slidable along the bed 25, the illustrated embodiment of the present invention is provided with'a table 36 (Figs. 1-5) of the usual integral construction, having a horizontal'top, front and rear walls, right and left side walls 3'! and 38, respectively, and the usual internal strengthening ribs herein shown as a pair 39 extending between the front and rear table walls and a single rib 49 extending between the side walls 3'! and 38. In order that the table 36 may re t won the bed 25. the front and rear walls of the table and the transverse rib 48 are provided wit a igned slots 43 (Fi s. 1, 3-5) which receive the bed guide member 35. and with this construction the table 36 may be slid onto the bed to a position for operat on in which the table rests beneath the platen 28; Rearward movement of the table may be limited by the abutment of its rear wall with plates 42 secured to and upstanding from the back of, the bed, and once the table is thus positioned upon the bed any tendency of forward movement of the former may be Prevented by means of bolts d3 (Figs. 2-5) which extend vertically up through the bed 25 at its rear in locations where they may substantially engage the inside face of the rear table wall. While the table 35 is a heavy element, means is preferably provided to insure that it will not tip forward, as will stripper-plate 1131(Figs. 1-6, 9-14) from' which depend posts 14, herein shown as nine in number, which are received, respectively, in a like number of pairs of aligned openings I and 18 formed, respectively, in the two plates 88 and B9, and around the posts 74 springs I? are coiled in interposition between the stripper plate 13 and the top of the base 60. The bottom of the base is provided with recesses 18 (Figs. 6, 10) beneath the pairs of openings and 1'6, and these recesses form shoulders 18 with the bottoms of passages 80 of less diameter located in the base 60 directly beneath the openings 15 and 16. The passages 88 slidably receive the posts 14, and screws 8! are threaded into the posts so that each screw abuts the associated shoulder '18. The stripper plate 13 is provided with the usual tube holes 82 (Figs. 2, 10-14) and with an open portion 88 (Figs. 2, 10-114) forming a clearance area, and in the illustrated embodiment of the present invention the normal level (Figs. 10 -11,.13-14) of the stripper plate 13 is such that its top surface is in the plane of the tops or cutting edges of the tubes To complete the stripper plate structure, it is provided with a gauge plate 84 (Figs. 1-3, 5, 9-14) having a front wall contoured for registry with correspondingedge portions of a pair of quarters 85, indicated in construction lines in Fig. 2, and there is also provided the usual clip construction 88 for maintaining the work pieces in position on the stripper plate. If desired, the gaugeplate 84 may be provided along the top of its front wall with forward projections 81 (Figs. 1-3, 5, 9-10, 13-14), formed by stamping the material of the plate at selected points, and these projections 81 overlie the edgings of work pieces, functioning to prevent any upward displacement of the edgings or to keep them flat if they tendto curl.

By reason of the above construction, the heads of the screws 8| limit the upward movement of the stripper plate 18 to the level stated, while the slidingfit' of the posts M in the passages 88 and the yieldin resistance of the springs i1 permit movement of the stripper plat toward the die block or base 68 under the influence of pressure, as provided by the downward stroke of the plunger 26. As a consequence, and asis well understood, when any work piece is mounted on the stripper plate 13 and-the die structure is on the table 36, descent of th plunger presses the stripper plate and the work piece downward to perforate the latter by means of the tubes 81, after which, upon the rise of the plunger, the springs Ti, previously compressed on the downward stroke of the plunger, force the stripper plate up to its normal position and in so doing effect the stripping of the work piece from the tubes 81.

In order to provide for marking guide lines on a work piece during the cutting operation, the present invention contemplates the association with the above-described structure of a marking die and actuating elements therefor. To this end, and with reference to Figs. 1-3, 5, '7, and 9-15, the illustrated embodiment of the present invention is provided with a plate 88 having upstanding therefrom edgewise as separate pieces strips 88 the tops of which taper to form marking edges 90 lying in a plane. Between and adjacent the strips 89 the plate 88 is provided with openings 9| (Figs. '7, 10-14) through which the tubes 61 freely extend, and for disclosure purposes the strips 89 are shown curved and bent into conformity to the design or arrangement formed by the tubes 61. The plate 88 is narrower (Fig. 7)

thanthe tube plate 68 so as to avoid'itsfour front and four rear openings 15, but has aniovere all size larger than that of the clearance open! ing 83 in the stripper plate so that portionsof the plate 88 extend between the stripper plate and the die block 60, i. e., so that portions of the stripper plate are superposed over the plate 88. In order to accommodate the stripper plate post 74 and its spring 1! which are-within the area of the plate 88, the last named is provided with an opening 92 (Fig. '7) aligned with the associated openings 15 and I8 therebeneath. i

The plate 88 normally'rests on the tube plat 88 as shown in Figs. 1, 9-11, and 13, but as will be hereinafter described, the plate 88, is mounted for movement vertically away from and back to this normal position of rest. In" order to guide the plate 88 in its vertical movement, the plate is provided with openings 93 (Figs. 2, 7, 13-14) each of which receives the upper split'end of a vertically depending post 94 (Figs. 2, 6-7, 9, 13-14) the posts being slidable in guide passages 85 (Figs. 9, 13-14) formed by aligned openings extending through th tube plate 68, the tube rest plate 89, and the base 68. As shown in Figs. 9-1-1 and 13, the strips 89 have such height that when the plate 88 rests on the tube plate 88, the plane of the marking edges 98 is lower than that of the tops or cutting edges of the tubes 61. Specifically, the plane of the marking edges 80 is herein illustrated only for disclosure purposes-as being slightly below the level of the bottom surface of the stripper plate 13.

In order to join the strips 89 to the base formed by the plate 88, resort may, of course, be had to solder.- It is preferred, however, to provide the plate 88 with rows of holes 88 (Figs. 10, 15) which may or may not be circular, each row conforming to the curve and/or bend which a strip 89 is to have, and then to form teeth or projections 91 (best seen in Fig. 15), as by sawing, punching, or milling, along the bottom of the strip, thereafter forcing the teeth into the holes 96 to secure them there frictionally and smoothing off any burrs or portions of the teeth which may extend below the level of the bottom of the plate. Th top portions of the strips 89 may be tapered to form the marking edges 90 either before or after the teeth 91 are forced intothe holes 98, but tapering after forcing is preferred since it will be found convenient to tap the top edges of the strips to start the teeth in the holes and then to turn the plate 88 upside down with the strips resting on some suitable uniformly yielding material, thereupon tapping or otherwise exerting pressure against the plate until the teeth 9! are forced home. The marking edges 90 may be continuous, as shown, or may each comprise spaced portions to provide broken lines. It will be appreciated, of course, that it is entirely within the scope of the'present invention to have the strips 88 and the plate 88 integral, as is the marking die shown in my said copending application, but since strip material and plate material are readily purchased as such, it willbe seen that the above-described construction is more easily manufactured than is integral type which requires considerable milling and machining of an originally thick plate to form a thin plate from which integral and accurately edged ribs or strip-like portions upwardly extend to provide marking edges.

The present invention contemplates that in the use of the above-described die structure themarking die formed by the plate or base portion 88 and the strips 89 shallbe elevated from its Figs. 1, 9-11, and 13 or normal retracted position of rest on the tube plate 68 in two different manners and for two different purposes, one for the application of marking substance, preferably a suitable ink, to the marking edges 90 since such application is not practicable when the marking edges 'are located below the tops or cutting edges of the tubes 61, and the other for moving the inked marking edges 90 into marking engagement with work pieces engaged with the stripper plate I3.

To achieve elevation of the markin die for the latte-r of the above two purposes, the present invention contemplates that the assembly 4? be provided with means forming a part thereof and actuable to raise the plat 88, attention here being called to the fact that for this purpose there is herein disclosed a lever construction which, while retaining the functions of that disclosed in my said copending application, is much simpler and sturdier and is more easily made. To this end the top of the die block or base 80 is preferably, although not necessarily, provided with elongated recesses. 98 (Figs. 7, 9-14) of identical construction, comprising a spaced pair located parallel to and adjacent the rear dge of the base andla spaced pair similarly located. with respect to the front edge of the base. Each recess 98 has parallel long sides and rounded ends, and the tube res-t plate 69- is provided with openings 99 which have the same shape as the recesses 98 and. overhe them, respectively, as the tube rest plate is supported on the base 60. The aligned recesses 98 and openings 99 form sockets for the reception of rocker-pins I00, each of which has projections IOI of reduced diameter extending from its opposite ends for location in the rounded ends of the sockets. As shown best in Figs. 11 and 12, the tops of the projections- I;0.'I lie slightly below the level of the top surfacev of the tube rest plate 69, and to hold the rocker-pins I in their sockets while permitting them to. rock freely, the cutting die base formed by the tube plate 88 is provided with elongated notches I02. (Figs. 7, 9, 11-12) the short ends of which overlie (Fig. 'l') the rounded ends. of the sockets and hence overlie the rocker-pin projections. I0 I. Extending inwardly from the long sides of the notches I02 the upper portion of the tube plate 68 is provided with elongated recesses [03 (Figs. 7, 9-14)- the inner portions of which underlie the plate 88, and

received fiatwise in the recesses I03 are the inner portions of levers I04 (Figs. 1-2, 6-7, 9-14) which are preferably not thicker than the depth of the recessses I03, and may be thinner, so that the lever inner portions underlie the plate 88 as it is supported by the tube plate 08. The levers I04 are made of resilient strip spring material, extend outwardly beyond the front and rear edges, respectively, of the base 60,, are preferably, although not necessarily, of equal length, and at points; between their ends are secured, as by rivets I (Figs. 7, 9-14) to flat surface portions I06. on the rocker-pins I00, these surface portions lying substantially in the plane of the bottoms of the tube plate recesses when the rocker-pins are in their normal or Fig. 11 position. Completing the die structure mechanism actuable to effect elevation of the marking die for work marking purposes, the stripper plate I3 i provided with depending front posts I01 (Figs. 1-3, 5-6, 9-H) and rear posts; I08 overlying the outer ends of the associated levers I04.

With the above arrangements, it will be seen that the tube plate 68 serves to hold the levers I04 wingably secured in the die structure 41 by reason of portions of the tube plate overlying the rocker-pin projections I01. It will also be seen that when the stripper plate 73 and the Work supported thereby descend, as under the influence of the plunger 20, the posts I07 and I08 press against the levers I04, thereby swinging their outer portions downward and simultaneously causinng their inner portions to swing upward, and that since the inner portions of the levers I04 underlie the plate 88, this swinging movement necessarily causes the inner ends of the levers to push the plate 88' and the strips 89 upward so that the marking edges 90 engage th work and mark it. Since the presence of the gauge plate 84 on the stripper plate 1'3 causes the portion thereof to which it is attached to flex downwardly (Fig. 1 2) under the influence of the plunger 26 before the remainder of the stripper plate descends, as is well known, the rear posts I 08 are shorter than the front posts I01 so that the inner ends of all the levers I04 will engage and exert upward pressure on the plate 88 simultaneously. In the particular die structure shown in the drawings the levers I04 have identical power, fulcrum, and work point locations. Should it be desirable, however, to vary any one or all of these three factors for a given die structure, or to vary the length of one or more of the levers I04 at either or both sides of the fulcrum thereof, or to vary the thickness of the gauge plate 84, it will be understood that the length differential between the posts I01 and I08 and also theloeation of the posts may be varied as required by these changed conditions to effect the simultaneity of engagement of the inner ends of the levers I04 with the plate 98.

In order to elevate the marking die so that the marking edges 90 are in a position to receive ink or other marking substance to the exclusion of the tops or cutting edges of the tubes 61, i. e., in order to elevate the marking edges 90 above the plane of the top of the gauge plate 84 and hence above the tops or cutting edges of the tubes 61,

a different elevating arrangement inthe die structure than that abov described is contemplated. More particularly, use is made for this purpose of the posts 94 which depend from the plate 88v and are received in the passages 95 which guide the vertical movements of the posts and hence that of the plate.

Referring to Figs. 6, 9, l3, and 14, the. lower ends of the pairs of posts 94 at each side of the plate 88 are secured to horizontal bars I09 which are freely received in slots IIO formed in the bottom of the base 60 of the die structure in parallelism with the sides thereof. The depth of the slots I I0 is preferably greater than the height of the bars I09, and to give even more space above the latter, the slots I I0 communicate upwardly with recesses lII formed in the base above the bars I09 and being slightly larger than the bars so as to be capable of freely receiving them when they are pushed upward, as will be described. As shown in Fig. 13, the length of the posts 94 is such that when the plate 88 rests on the tube plate 08, the bottoms of the bars I09. do not extend below the level of the bottom of the base 90. But it will be appreciated by comparing Figs, 13 and 14 that when the bars I019 are pushed upward, the marking edges 90 may be elevated, by reason of the elevation of the plate 88 and the posts 94, above the level of the tops or cutting edges of the tubes 6! and also above the plane of the top surface of the gauge plate 84, this result being possible because the distance between the tops of the bars I69 and of the recesses II: is greater than the distance between the plane of the top surface of the gauge plate 84 and the plane'of the marking edges 95.] as the plate 83 rests on the tube plate 68.

In order to elevate the bars I69 and so elevate the marking die to place the marking edges 96 in the advanced position just described, the present invention contemplates that this result be achieved by mechanism which is positively actuable while the die structure is supported on the rails BI and 62 in advance of the machine bed 25 i. e., in advance of the table 36. But the present invention also contemplates that this mechanism shall be actuable for this purpose by operative connection with the mechanism for depositing marking substance on the marking edges 90, and in view of this compound structure and mode of operation, it is deemed best to proceed first with a description of the bar-elevating mechanism, then with a description of the depositing mechanism, and then with a description of the operative connection between the two.

Accordingly, the guideway plates 48 and 49 are provided belowthe level of the rails BI and 62 with'aligned openings which receive the opposite ends of a cam shaft I I2 (Figs. 1-5) the outer portions of which extend beyond the outer surfaces of the plates, as shown best in Figs. 1 and 2. Between the plates 48 and 49 the cam shaft II2 carries two cams II3 of identical construction, each comprising a body portion secured to the shaft by a set screw I It! extending into a passage (Fig. 5) formed in the shaft and a peripheral portion of reduced width having an arcuatecam surface IIS of about 180. The cams II3 are alignedalong the shaft I I2 and are spaced apart so as to have their cam surfaces II5 located, respectively, in the vertical planes (Fig. 1) of the slots II!) in the bottom of the die base 60, i. e., of the bars I09 depending therein. The cams [I6 are normally in a deactuated condition, i. e., .lecated entirely below the level of the rails 6| and 62 (Figs. 1, 3, 5), but the radius of the cam surfaces II 5 is such that when the cam shaft I I2 is rotated to actuate the cams, as will bedescieibed, the cam surfaces extend (Fig. 4) above the level of the rails 65 and 62, i. e., above the level of the bottom of the die base 69, so that they may engage and push up the bars I69 and so' elevate the marking die. Specifically, the radius of the cam surfaces I I5 is such that when they engage the bottoms of the bars I69 and push the "bars up into the recesses III, the plate 68 is elevated (Fig. 14) so that the marking edges 60 are above the plane of the tops or cutting edges of the tubes 61 and also above the plane of the upper surface of the gauge plate 86. The tops of the bars I69 preferably do not engage the tops of the recesses I I I, and the upper surface of the plate 88 preferably does not engage the under surface of the stripper plate I3, when the bars are elevated by the cams II3 as shown in Fig. 14, this arrangement being provided so that there is no danger of the cams lifting or tilting the die structure as a whole with respect to the -rails GI and 62 and so as to allow maximum tolerance in selecting the radius for the cam surfaces H5.

As indicated in Fig. 4, the cams H3 are operative to elevate the bars I69 when the die structure 41 is moved to a proper position forward on'the railsfilj and, 62, aheadof the machine Joed 25, i e., aheadj of the; table 36;10. insure that this forward movement of the die structure will not be too-great, i. e,,:to insure that" the die structure willqbe in such location that the bars I69 will overlie the cams II3'so-that the latter may perform'their elevating function, the plates 48 and ts are'provided with aligned'stops each of which comprises a plate I I6 (Figs. 1 5, 18) secured to the inner face of its associated plate 48 or ilfi by a bolt III. The stop plates II6 extend above the levelof the rails EI and 62, i. e., above the level of the bottom of the base 60 and in" thepath of movement thereof, and to'insure thatthe stop plates do not turn on thebolts N1, the top of each plate may be provided with an outward lip IIBwhich rests on the associated rail 6i or 62 and preferably is spaced from the adjacent plate wall thereabove, as shown besl in'Fig. 18. Y

In order to deposit marking substance on'the marking edges 90 whenelevated by the'cams I I3, a pad may be brought into engagement with the edges to ink them orthe edges may bemanually provided with marking substance in any other manner, but the present: invention contemplates that preferably a reciprocable carriage be provided for holding a roll to deposit marking substance on the'marking edges by rolling contact therewith. To this end, and-,referring to Figs. 5, 8, and 18, the-slots 63 and 64 formed in the guide- Way plates 48 and 49, respectively, eachreceive a horizontal block I I9 which slidably engages the top and bottomwalls of its associated plate slot.

The slide blocks H9 each extend inwardly from the outerfaces ,of the plates 48 Sand 49 to the inner faces thereof above the level of the rails 6.Iv and 62, .andextending from the vertical side walls of the plate recesses 65 and 66 inwardly to saidinner plate. faces the opposite end portions of each slide block IIB'are provided with upper and lower integral lips I20 which slidably engage the top and bottom recess walls and slidably abut the vertical side walls thereof to prevent movement of the block's H9 outwardly through the slots 63 and 64.v Connected'as by machine screws and pins to theouterfaces'of the slide blocks H9 and. slidably. enga ing the 'outerfaces of the plates 48 and 49; respectively, are the lower end portions of upstanding plates m (Figs. 1,3-4, 8,12)

and I22 (Figs. 1, 5), and at their upper ends these plates areconnected front and rearby transverse rods I23 (Figs. 1+5, 17) which extend across the apparatus and at their oppositeends have slots into which the plates I2 I and I22 lit for attachment by screws. With this arrangement it will be seen: that a carriage is formed which'is're ciprocable horizontally along the guideway plates 48 and 49by reasonof the sliding fit of the slide blocks 'IIBin' the slots 63 and 6 I, which is of rigid construction byreasonof the connections of the plates I2I and I22 both to the slide blocks'II9 and to the rods I23, and'which-is r'novably secured in the apparatus by reason of the abutment of the block lips I20 with the vertical sidewalls of the recesses 65 and 66. 3

.Above the level of thetops of the guideway plates and 49 the plates-I2I and I22 are each provided with'spaced front and rear ways I24 (Figs. 3-5, 8)'and I25 .whichreceive front and rear slide blocks I26 and I2I, respectively, each havinglips extending from the opposite sides of their inner and outer faces so that the slide blocks can move only vertically in the Ways, Each slide which extends upwardly from the top of a passage I29 (Fig. 8) formed one in the bottom of each of the ways I24 and I25, and within the passages the pins are of greater diameter to form shoulders I30 and are hollowed'out to receive the upper ends of upstanding helical springs I3I the lower ends of which rest on the bottoms of the passages I29. Ferrules I 32 threaded in the upper portions of the passages I29 serve as abutments for the pin shoulders I39 and hence permit downward movement of the pins I28 against the yielding resistance of the springs I 3] while preventing the escape of the pins from the passages. The plates I2I and I22 are cut away at their upper rear ends to pivotally receive, as by a bolt I33, ears I34 (Fig. 1'1) and I35 (Fig, formed at the back of hinge plates I36 and I31, respectively, which overlie the tops of the plates -I 2I and I22 and may be secured at the forward ends thereof by knurled headed screws I38, and in order to maintain the slide blocks I26 and I21 pressed against the pins I28, the hinge plates I36 and I31 are each provided with a pair of front and rear knurled headed screws I39 (Figs. 2-5, 8) and I40 which extend downwardly into engagement with the respective slide blocks I26 and I21 and areheld in a position of adjustment by lock nuts Journaled in the front slide blocks I26 are the reduced end portions of a shaft I42 (Figs. 1-2, 5, 8, 17) provided with collars I 43 between which the shaft is of greater diameter and may be provided with longitudinal ribs I44 (Fig. 5) which serve to hold against rotation with respect to the shaft a preferably sponge rubber cover of cylindrical exterior and substantial thickness so as to form a marking substance applying roll I45. J ournaled in the rear slide blocks I21, and at a level somewhat higher than that of the shaft I 42,

are the reduced end portions of a shaft I46 (Figs.

2, 5, 17) which is parallel with the shaft I42 and has a preferably smooth rubber cover so as to form a roll I 41. With reference to Fig. 5 it will be seen that the roll I41 exerts a slight pressure on the roll I45, thereby being rotatable by the rotation thereof, and functions not only to spread along the roll I45 marking substance applied thereto in any suitable manner but also to squeeze the roll I45 to bring to its surface marking substance caught in its voids. Since the function of the roll I45 is to deposit marking substance on the marking edges 90, and since the marking edges are intended to receive marking substance when the bars I09 are elevated by the cams II3, it will be seen that the lowermost element of the periphery of the roll I45 should preferably be located slightly below the plane of the thus elevated marking edges 90 and of course not above it. This is achieved by turning the adjusting screws I39 to move the front slide blocks I26 and therefore the roll I45 to the proper level, after which the adjusting screws I40 are turned to move the rear slide blocks I21 and therefore the spreader roll I41 to the proper level so that the latter engages the roll I45 as stated above.

To facilitate pulling the roll carriage forward to cause the deposition of marking substance on the marking edges 90, the above-described carriage construction may be provided with a handle I48 (Figs. 1-5). The opposite ends of the handle are provided with pins I49 which are received in upstanding ears carried by arms I50 located one at each end of the handle and having their opposite ends provided with bosses I5I the outer ends of which terminate adjacent the plates I2I and I '22 and receive the front and rear rodsI 23 so as to be supported thereby.

- elevation of the marking edges to a-position to receive marking substances. But the present invention also contemplates that preferably means be provided which automatically returns the roll carriage and effects lowering of the marking edges so that the carriage need not be pushed back manually, this construction and mode of operation being desirable, although not necessary, because of the speedier use of the apparatus resulting therefrom.

Referring to Figs. l-5 and 8, the illustrated embodiment of the present invention is provided with a pair of'L-shaped, upstanding plates I52 and I53 of identical construction. The short bottom legs of these plates extend rearwardly in engagement with the outer faces of the blocks 50 and 5|, respectively, and are secured thereto by machine screws I54, while the upstanding portions of the plates I52 and I53 engage flatwi-se the outer faces of the guideway plates 48 and 49, respectively, and are secured thereto by machine screws I55. This type of securement serves not only to hold the plates I52 and I53 securely in position but also to maintain parallel the portions of the plates 48 and 49 just ahead of the table 36. The front faces of the plates I 5-2and I53 are aligned with the rear faces of the plates I2I and I22, respectively, and thus form stops for limiting their movement and that of the roll carriage as a whole. Associated with the plates I52 and I53 are elements of corresponding construction for each plate but located as groups at their opposite outer sides of the plates 48 and '49, and since these elements are corresponding for each side a description of those at the outer side of the plate 48, for example, will serve as a description of those at the outer side of the plate 49. The L-shaped plate I52 securedto the block 56 and the guideway plate 4 8 receives the split shank of a bolt I56 the head of which extends outwardly from the inner face of the plate 48 in which it is mounted, and the shank of the bolt I56 extends outwardly beyond the outer 'face of the plate 48 and from that point receives, in out ward order, a circular, spring-retaining plate I51, a cup I58 the open end of which engages the plate I 51, the lower end of an upwardly and forwardly extending lever I59 secured by rivets I69 to the closed or outer end of the cup I58, and two nuts I6I which function to maintain the foregoing elements mounted on the bolt I56. The cup receives a spiral spring I62 the outer end of which (Figs. l-4, 8) extends outside the cup I 58 through a slot in the wall thereof and is bent into engagement with said wall, while the inner end of the spring I 62 is located within the cup in the slot I63 formed by the splitting of the shank of the bolt I56. stored with power as the level" I59 is in its normally retracted or Fig. 3 position so as to effect a rearward push on the lever, and the direction of convolution of the spring I62 is such that it becomes further wound and stored with power as the lever I59 is swung forwardly, or to the left, viewing Fig. 4. I

The spring I62 is partially wound or Pivotally connected to the upper end of the lever I59 is the upper end of a link I64 (Figs. 1-5, 8) which extends downwardly and forwardly and has its lower end pivotally mounted on the smooth shank of a stud I65 threaded into the car- 'riage plate I2I, a washer I66 being interposed between the link I64 and the head of the stud. Behind the link I64 the stud shank receives the rear end of a second link I61, and between this link end and the carriage plate I2I the stud I65 carries a spacing collar I68 (Figs. 1-2, 8). Disregarding for a moment the end of the second link I61 and bearing in mind that the plate I53 secured to the block I and the plate 49 is also provided with a split bolt I56 and parts corresponding to those above described, it will be seen that by reason of the springs I62 and the connection between the levers I59 and the studs I65 afforded by the links I64, the plates I2I and I22 (and therefore the roll carriage) are normally in a rearward or retracted position in which they engage the front faces of the plates I52 and I53, respectively, and that when the roll carriage is pulled forwardly along the guideway plates 48 and 49, the upper portions of the levers I59 are swung forwardly so that the springs I62 are stored with more power than they normally have, which additional power is released when the carriage is released so that the springs automatically pull the carriage back until the rear faces of the plates I2I and I22 again engage the plates I52 and I53.

Referring again to the second link I61, its forward end is pivotally connected to the upper end of a second lever I69 (Figs. 1-5), and this lever is loosely fulcrumed at an opening I19 therein (Figs. 3-4) which receives the end portion of the cam shaft II2 projecting outwardly from the plate 48. At its lower end the lever I69 is pivotally connected by a stud I1I to the lower end of an arm I12 (Figs. 1-5) the upper end of which is bossed to receive the projecting end of the cam shaft H2. The shaft is provided with an opening for the reception of a set screw I13 carried by the boss, and the foregoing construction is completed by a spacing collar I14 (Figs. 1-2) mounted on the stud HI and interposed between the lever I69 and the arm I12.

In view of the foregoing, and again bearing in mind that the elements just described have their counterpart at the outer side of the guideway plate 48, it will be seen that when the roll carriage is pulled forward, the studs I65 push for- -wardly on the links I61 which thereupon swing the levers I69 on the cam shaft H2 and hence effect its rotation by reason of the arms I12 being fast on the cam shaft H2 and pivotally connected to the levers I69. As a result the cams II3 are turned or actuated to bring their cam surfaces II5 above the plane of the rails BI and 62, i. e., above the level of the bottom of the bars I09 as the die structure engages the stop plates H6, and so effect the desired elevation of the marking edges 99 to a location for the reception of marking substance from the roll I45. The cams II3 begin to rotate as soon as forward movement of the roll carriage is initiated, and for this reason the cams are so located .on the cam shaft I I2 that the cam surfaces II5 engage and push up the bars I99 before the roll I45 reaches the rearmost marking edges 99, and by giving the cam surfaces an extent of some 180, maintenance of the cam surfaces in engagement with the bars I09 is assured so that the forwardly moving roll I45 passes over all the ,marking edges 99 in rolling contact therewith. By the same token it will be seen that when the the rearmost marking edge.

Consideration of the entire structure thus far set forth will show that an operative organization has been provided by which the marking edges 90 may receive marking substance for transfer to a work piece. The above-described table and guideway structure may be installed in a cutting machine as a unit, thereby making it a combined marking and cutting machine. The die assembly 41 is a self-contained structure and may be provided with the usual handle (not shown) and be located in the apparatus with the die block or base 60 on the rails 6| and 62 and engaged with the stop plates H6, and assuming that theroll I45 is Properly sup-plied With ink or other marking substance, an operator can pull the roll carriage forward, as by the handle I48, whereupon the cams II3 will effect elevation of the marking edges 99 and the forwardly moving roll I45 will engage them by rolling contact and deposit marking substance on them. Upon release of the carriage handle I48 the springs I62 will effect rearward movement of the carriage, the roll I45 thereupon passing over the elevated marking edges a second time and the cams II3 then being deactuated, i. e., rotated out of engagement with the bars I69. As the bars then drop by gravity and with them the plate 88, the marking edges will assume their normal position below the level of the tops or cutting edges of the tubes 61, and while the die structure remains on the rails 6! and 62 the operator may secure work pieces on the stripper plate 13 in proper position, then push the die structure along the rails rearwardly and onto the table 36, i. e., into operative position in the machine, beneath the platen 28, and thereupon efiect both cutting and marking of the work by depressing the pedal (not shown) forming part -of the cutting machine and connected to its clutch. The cycle of operation is completed by the operator pulling the die structure forward by its handle and into engagement with the stop plates I I6, whereupon removal of the marked and cut work leaves the apparatus in condition for use in the above-described manner with further work pieces.

But while the above mode of operation is entirely possible and practicable, it is not as fast as may otherwise be the case, and in addition to this, it will be appreciated that since the roll 1 I45 engages the elevated marking edges 96 both when the roll moves forwardly and when it moves rearwardly, unless the operator forcibly holds the die structure, as by its usual handle (not shown),

against the stop plates II6 when the roll carriage is released, the roll I45 might pull the whole die structure with it during this rearward 'movement, thus not only drawing it away from the cams H3 and hence making it impossible J during this rearward movement to place further marking substance on the marking edges'to insure that all will have a proper amount but also requiring the operator to pull the die structure forward again to a convenient position for placing work pieces upon it.

In order to avoid displacement of the die structure 41 by the roll I45 during the rearward movement of the roll carriage, and to provide for speedier operation than that set forth above, the present invention contemplates that means be provided by which an operator, without using his hands, can draw a die structure out of operative positioning in the machine and into engagement with the stop plates H6 and can hold the die structure there during both forward and rearward movement of the roll I45 in engagement with the marking edges '90. The present invention also contemplates in this connection that means be provided which automaticall returns the die structure to its operative positionin the machine, thereby rendering it unnecessary for an operator to push the die structure there with his hands after he has mounted work pieces on it.

To these ends the die block or base 68 of the die structure is provided at its front center with a forwardly extending screw having an eye I15 (Figs. 1-2, 5-7, 9-14) and functioning to support a stop member I18 the lower portion of which extends downwardly below the level of the bottom of the die base 60. Releasably clipped to the eye I is one end of a cord I11 (Figs. 1-5) which extends forwardly for reception in the groove of a sheave I18 rotatably received on the rod 51 at the front portion of the guideway plates 48 and 49. As shown in Fig. 5, the rod 51 is provided with a peripheral groove I19 for receiving a set screw I80 carried by the sheave I18, and with this construction the sheave is maintained centrally located on the rod 51 in alignment With the eye I15. Below the sheave I18 the cord I11 extends to a point of attachment at the front end of a lever I8I (Figs. l-3, 5) the rear end of which is pivotally mounted on a pin I82 carried by the ears of a bracket I83 mounted on the front of the machine bed 25. Adjacent the bracket I 83 the lever I8I is provided with openings I84 by any one of which the upper end of a link I85 may be pivotally secured to the lever NH, and the link I85 extends down.- wardly and forwardly and at its lower end is pivotally connected to a lever I86 (Figs. 2-3). In turn the rear end of the lever I86 is pivotally connected to a bracket I81 suitably secured to the floor I88, and the front end of the lever I86 is provided with a pedal I89. Completing this structural arrangement, the die block 68 is provided at its rear with spaced screws having eyes I99 (Figs. 3, 5-7, 10-14) to each of which is releasably clipped a cord I9I (Figs. 1-5), and the cords extend rearwardly over sheaves I92 pivotally mounted inalignment With the eyes I99 upon brackets I93 secured to the rear wall of the table 36. The lower ends of the cords I9I are attached to a depending weight I94 which is heavier than the die structure 41 and is sufficiently heavy to overcome the pull of gravity on the levers I8I and I85 and the link I85 so that the pedal I89 is normally raised as shown in Fig. 3.

With the foregoing structural features, the Weight I84 yieldingly tends to maintain the die structure 41 normally located on the table 38, and the stop member I16 limits the rearward movement of the die structure so that the weight over, since the pedal I89 is. easily maintained depressed by the foot as long as desiredthe length of the cord I11 preferably being such that the pedal substantially engages the floor I88 when the die structure base engages the stop plates I IIi-maintenance of the foot on the pedal when the roll carriage is released prevents the engagement of the roll I45 with the elevated marking edges 98 from resulting in the drawing of the die structure 41 rearwardly along the rails 5| and 62 and hence away from the cams I i3. As a final point, release of the pedal I89, after the marking edges 99 have been provided with marking substance and have been lowered to their normal retracted position and after work pieces have been secured on the stripper plate 13, permits the weight I94 to descend and so draw the die structure along the rails and into its operative position in the machine as determined by the stop member i18. It will be appreciated that since the lever I8I is a lever of the third class, the nearness to its fulcrum I82 of the upper end of the link I85 results in a relatively short downward stroke of the pedal I88 producing a relatively long downward swing of the front end of the lever I8l, and with this arrangement the pedal need not move through an arc commensurate with the distance between the front of the table 36 and the rear or abutment faces of the stop plates H6.

While the above-described structure provides that the lever I8! is pivotally secured to the bed 25 of the machine, it is not necessary that this mounting location be selected, and where a press machine is used the bed of which is not adapted to receive the bracket I83 or its .equivalent or Where it is not convenient or desired to tap the machine itself for reception of such a bracket, the lever i8l may be pivotally mounted on the bench 34 below the machine frame, a support I95 (Fig. 16) being bolted to the front of the bench as a mounting for a bracket I96 the ears of which pivotally receive the rear end of the lever I8l for this purpose. The operative connection of the lever I8I with the pedal I89 will not be changed in principle with such an arrangement, 1 as it W111 be appreciated that although the bench stripper plate descends, the posts I 81 34 is below the bed, the lever I8! will preferably be upwardly and forwardly .tilted (Fig. 16) so that its front end will have a sufficiently long swing. It may be pointed out'also that in either of the above arrangements for operatively connecting the levers I8I and I88 it is not essential that the link I85 be made of stiff material, for a cord will function as well.

It has been brought out above that when the plunger 25 descends, it presses the Work pieces and the stripper plate 13 downward, thereby causing the tubes 51 to pierce and cut the work. It has also been brought out above that as'the and I98 depending therefrom press down the outer portions of the levers I04, thereby causing their inner portions to swing upward and so elevate the plate 88 from its normal retracted position, with the result that the marking edges 98 engage work pieces that are descending. In view of the two facts that the work pieces are supported by the upper surface of the stripper plate, which upper surface is normally substantially in the plane of the tops or cutting edges of the tubes 61 and above the plane of the marking edges 99, and that the marking edges rise intoengagement with work pieces that are descending, it Will be seen thatthe initial engagement plane of the work pieces and the marking edges 99 is somewhat lower than that of the tops of the tubes and somewhat higher than that of the normal retracted level of the marking edges. As a consequence, the efiect of the pressure of the plunger 25 on the stripper plate 13 to efiect engagement of the work pieces and the marking edges is to cause the latter to approach the plane of the tops of the tubes 6?, i. e., to cause a decrease in the normal spacing between the plane of the tops of the tubes and the plane of the marking edges. The marking edges thus do not actually reach the level of the tops of the tubes because the descending work pieces have already passed that level and have been at least partially pierced by the tubes by the time marking engagement with the marking edges occurs.

It will be understood that this same result will occur if cutout or edge cutting elements are ernployed with or in place of tubes, and it will also be seen that. as a result of this partial piercing of the work pieces prior to their being marked the present invention, like that of my said copending application, does not rely, for the maintenance of the work pieces over the stripper plate clear ance opening 83 in proper position for marking,

,merely upon the customary squeezing action resulting from the work pieces being between a resiliently mounted stripper plate and a pressure surface or platen. Supplementing this squeezing action, which can exist only outside the clearance opening 83 so far as the stripper plate is concerned, is the impalement by the tubes '5 of the portions of the work pieces overlying the opening 83, and since the tubes are located adjacent the strips 89,'as shown in Figs. 2 and 7, the portions of the work pieces overlying the opening 83, in being impalingly pressed onto the tubes before marking can occur, are held by the tubes from any creeping with respect to the marking edges 90. There is thus no danger of the marked lines being blurred or thick as a result of creeping of the work. 7

The above approach of the marking edges 90 to the plane of the tops of the tubes 61 takes place shortly after the work pieces and the stripper plate 13 begin to move toward the die block 60 and impalement of the work pieces on the tubes is initiated.

thickness of the work pieces is such that engagethemselves of resilient spring material.

If the throw of the plunger 26 in the herein illustrated embodiment or the ment of the latter with the marking edges 90 the levers I94 will be released and the marking die formed by the plate 88 and the strips 89 will fall by gravity to its normal retracted position, and only the marking die, with the attached posts 94 and the bars I09, will exert any downward pressure on the levers it. If, however, the throw of the plunger 26 in the herein illustrated embodiment or the thickness of the work pieces is such that when engagement of the latter with the marking edges 96 occurs the plunger has not yet reached the end of its downward stroke, it is obvious that the plunger, acting through the stripper plate 13 and its posts l0! and I88, subjects to downward pressure not only the outer portions of the levers 34 but also the elevated marking die itself and the upwardly swung inner portions of the levers. As some part of the die structure would undoubtedly break or give way under these conditions if the connections between the plate 88 and the levers comprised a solid, unyielding construction, accommodation to prevent breakage is provided by making the levers Since the inner ends of the levers are spaced above the tube plate 68 when the inner portions of the levers are swung upwardly, it will be seen that space is provided for the downward flexing of the inner portions of the levers toward the tube plate, which flexing makes possible the descent of the marking die under the influence of the plunger. The marking die ofthe herein illustrated embodiment is thus during movement both upwardly and downwardly mounted upon supports, i. e., the levers I0 5, that are resilient and yielding. 1

Upon elevation of the plunger 26, the stripper plate 13 is released and this is accompanied by the stripping action of the work pieces from the tubes 61 and the eventual resumption of the marking die to its normal retracted position. But in those situations in whichthe marking die is pressed downwardly against the yielding resistance of the downwardly flexed inner portions of the levers Hit as the plunger 26 descends, it will be seen that as long as such downward flexing continues during upward movement of the plunger, so long will the inner portions of the levers exert upward pressure on themarking die. In view of this operation, it will be seen that the downwardly flexed inner portions of the levers, acting throughthe marking die, cause the marking die to exert stripping pressure upon the work as the plunger rises, and this stripping pressure,

being exerted within the opening 83 in the strip- I01 and IE8 depending from the stripper plate which swing the levers Iflfi to elevate the marking die into engagement with the work and hold it so engaged when the marking die thereafter descends and flexes the inner portions of the levers during further descent of the plunger. The stripping pressure exerted by the flexed levers against the marking die is preferably'less than that exerted by the springs Tl against; the stripper plate, and this is achieved by making the levers of spring material which, in the operation of the die structure, offers less resistance to flexing than do the springs 11 to compression. With further reference to the action of the levers Hi4, it will be appreciated that since these levers are not attached to the marking die, the engagement of the inner portions of the levers with the plate 88 is always slipping or wiping one so that these inner lever portions engage successive- 1y different areas of the under surface of the plate 88 both when it is rising and as it descends, and regardless of whether stripping pressure is being exerted by the levers or not. By reason of this wiping contact with the plate 88, the vertical guiding action of the passages for the posts 94 is not interfered with as might be the case were no wiping or sliding arrangement provided, and as a consequence there is no tendency for the marking die. to move laterally in engagement with the work and hence no danger of the marked lines being blurred or thick as the result :of such movement.

.:f. In view'of the above description of both structural and operative features of the illustrated embodiment of the present invention, it is believed that little need be added by way of summary of the operation of the embodiment as a whole. ,Once the cords Ill and MI are attached to the --.die structure, the latter will assume its normal or operative position in the machineon the table in the illustrated embodiment. But since the .pedal mechanism functions to pull the die struc- ,ture forward into abutment with the stop plates II6 and since the weight I94 functions to pull the die structure back onto the table, it will be seen that a safety measure is produced in that there is no occasion for an operator to place his hands under the platen 28. In fact, the only occasion for an operator even to reach toward the press machine when the apparatus is set up for use is to grasp the handle I48 to pull the roll carriage forward, and he need not push it back since the springs I62 take care of that automaticaily when the handle M3 is released. There is no danger of the table 36 and the guideway formed by the plates is and 19 tipping forward :under the weight of the die structure when it is pulled forwardly on the rails El and 62, as the bolt 44 received by the openings 45 in the rear wall of the table 3% prevent such a result.

It will be appreciated that instead of having the front faces of the plates I52 and I53 form stops to limit the rearward movement of the roll carriage, this result could be achieved by having the slide blocks H8 abut the rear closed ends of the guideway slots 63 and E4. The disclosed stop arrangement is to be preferred, however, since strain on the apparatus inherent in the use of stops is thereby better distributed. No stops corresponding to the plates I52 and IE3 are herein provided for limiting the forward movement of the roll carriage as such stops have been found to be unnecessary. Marking dies do not usually extend forwardly of the die blocks or bases of die structures, and as the stop plates IIS are located well rearwardly of the front ends of the slots 63 and as, an operator can easily tell by 7 view how far forward the roll carriage need be pulled to insure that marking substance is applied to the foremost marking edges. Should situations arise where forward stops are desirable, however, the slots 63 and 64 may be made sulficiently short to insure that the slide blocks II9 will abut their forward ends, or preferably the outer faces of the guideway plates 48 and 49 may be provided with stop members aligned with the plates I2I and IE2. It will also be appreciated, as more fully set forth above, that it is entirely within the scope of the present invention to use cutout, edging, or pinking dies in the place of or in association with the tubes 61 in the herein illustrated, self-contained die structure, and it is obvious that the pedal and weight mechanism herein disclosed may be used where a given die structure embodies only marking or only cutting dies.

In addition to the improvements noted above which the present die structure makes over that disclosed in my said copending application, certain other improvements are herein involved. The structure of my said copending application embodies the use of stationary cams for elevating the marking die through contact with elements corresponding to the bars I09 of the present invention. But as the cams are stationary the marking edges remain elevated after the roll carriage has been retracted, and as a consequence it is necessary for an operator to push the die structure off the cams before work pieces can be mounted on the stripper plate, and then to give the die structure a second push to place it on the table. The present invention, by providing in the illustrated embodiment for movable cams which are operatively connected to and controlled by the roll carriage, which is 'operatively connected to the levers I 59, insures not only that the marking die will drop upon retraction of the roll carriage, thereby rendering it unnecessary to move the die structure part way rearward in order to mount work upon it, but also that only one movement of the die structure is necessary to transfer it to its operative position in the machine from the point Where the marking edges receive marking substance, thereby making for speedier use. The present invention,

by not requiring that an operator pull a die structure forward in order to pull a roll carriage forward, and by not requiring that an operator reach over or around a partially advanced roll carriage in order to remove cut and marked work pieces from the stripper plate, as are modes of operation of the particular structure disclosed in my said copending application, thus requires much less physical exertion on the part of the operator and hence minimizes fatigue. It will be noted further that with the die structure in its outer position, the finished work can be removed and new work can be placed on the stripper plateand gauged, without obstruction of the said plate by projecting marking edges. This supplies a single station for all work handling operations. In the former patent of applicant the work must be withdrawn from the stripper plate after decoration before the die assembly passes over the stationary cams which elevate the marking die, and projects the marking edges to a position of pushing the work off of the stripper, thus smearing the work or at least making withdrawal of the work without smearing it a delicate operation. In like manner the die assembly must be moved away from inking position before new work is mounted on the stripper plate. By using a movable cam for the marker, and coupling up the ink roll carriage with that cam for conjoint operation, the above shortcoming of the embodiment illustrated in the patented structure is avoided.

Nothing herein explained is to be interpreted as limiting the present invention inthe scope of s application to use in connection with the particular structure or the particular mode of operation or both which have been selected herein for purposes of explanation and illustration.
